man i really can't help but not get family friendly vibes when a smaller yukkuri is inside a bigger yukkuri mouth, call me worrisome, but it really feels like something bad will happen.
It probalby won't be the case, but i really get the vibes each time i see a scene like that in any pic, even in the most blatlantly family friendly stuff. Maybe too many "get into the mouth, accidental chomp" jokes for me.
most of the images before the first server move didn't get their tag histories updated properly, so the tag histories didn't save. Only thing you can do is retag it which only takes a few seconds.
